Description: FOOD PRODUCTS WITH IMPROVED STRENGTH Description Background Food products derived from cereal grains such as wafers, (e.g., ice cream cones), crackers, cookies and cereals represent a fragile, crisp food system prone to breakage during manufacture, shipping and handling. This results in economic losses to the manufacturer and reduced product. It would greatly benefit the food industry to provide a means for improving the structural integrity of food products prone to breakage, without compromising the taste and sensory profile of the resultant food products. Summary of the Invention The present invention relates to food products derived from cereal grains, comprising a fiber with long, insoluble fiber strands which when present in the food product improves the overall strength of the product and its textural attributes compared to a food which does not contain said fiber. Preferred foods that can be strengthened with the insoluble fibers include edible wafers for frozen desserts and refrigerated novelties (e.g., ice cream cones), and formulated foods which include extruded foods, baked foods, puffed foods and snack foods (e.g., crackers, cookies, cereals and tortillas) . The fiber functions to strengthen the food product regardless of its final molded, extruded or puffed shape. As described herein, the fiber can be any fiber derived from a plant or microbial source which has a high content of insoluble dietary fiber. Only a small amount of fiber is required to strengthen the structural integrity of the final food product. The present invention further relates to a method of improving the strength and textural integrity of the food product to reduce breakage during manufacturing and subsequent handling of the food product. The method comprises admixing a fiber having long, insoluble fiber strands to the food formulation, to thereby improve the strength and textural integrity of the food product. The food product of the present invention can be used in the food industry, such as the ice cream novelty industry, baked goods industry or snack food industry to strengthen the structural and textural integrity as well as the overall quality of the food product, compared to similar food products which do not contain the fiber. Brief Description of the Drawings Figure l is a graphic illustration comparing the results for the storage modulus (C) and the loss modulus (G") for the strips from the control ice cream cones and the ice cream cones prepared with OPTA™ oat fiber 770. Figure 2 is a graphic illustration comparing the break force required for the control ice cream cones and the ice cream cones prepared with OPTA™ oat fiber 770. Detailed Description of the Invention The present invention is based on the discovery that incorporation of fiber into the matrix of a food product derived from cereal grains strengthens the structural integrity of the food product due to the large amorphous structure of the fiber particles. The addition of the fiber in the food product results in a food product with more rigidity and structural integrity. Consequently, breakage of the food products of the present invention occurs to a lesser extent than the food products currently available on the market. Foods that can be strengthened by incorporation of the fibers into their formulations are those which are fragile and are susceptible to breakage, in the absence of the fiber, during normal manufacturing and handling conditions. Preferred foods of the present invention are edible wafers for frozen desserts and refrigerated novelties (e.g., ice cream cones) and formulated food systems which include baked foods (e.g., cookies), snack foods (e.g., corn chips) and extruded foods, such as cereals (e.g., puffed, flaked or extruded) products. Normal breakage due to lack of structural integrity can be minimized in food supplies, other than yeast leavened products, such as Melba Toast, using the fibers as a means of reinforcing the food product. Only a small amount of fiber is required to strengthen and reinforce some food products, such as edible wafers (e.g., ice cream cones). The amount necessary can be readily ascertained as being that amount which is suitable to strengthen but does not compromise sensory properties of the product. In instances in which a small amount of fiber is required, preferably the amount of fiber will be from about 0.2 to about 10% by weight, with from about 1 to about 2% being most preferred, to yield a product that is structurally superior to like product which does not contain the fiber. However, some food products, such as those prepared from wheat or corn meal extrudates (e.g. tortillas) , require larger amounts of fiber to strengthen and reinforce the food product. In these instances, the preferred amount of fiber will be from about 1 to about 25% by weight, with from about 2 to about 10% being most preferred, to yield a product structurally superior to like product which does not contain the fiber. The strengthening amount of fiber may be slightly higher or lower than the preferred range depending upon the type of fiber used and the type of food product being strengthened, but determination of the strengthening amount would not require undue experimentation. The uniqueness of the food product of the present invention is related to the presence of relatively long, insoluble fiber strands that reinforce the food product and enhance the firmness/crispness of the initial product. Generally, the long, insoluble fiber strands range from about 100 to about 800 microns. In a particular embodiment, the length of the insoluble fiber strands used in the food product of the present invention is about 450 microns. In addition to length, the particle size of the insoluble fiber strands of the present invention is important. One method of determining the correct length and particle size of the fiber strands is by screen analysis using US Standard (USS) mesh screens. For example, the criteria for determining acceptable fiber length and size for the present invention using screen analysis is given below: USS mesh screen % fiber through screen 50 (course mesh) 98 100 (medium mesh) 85 200 (fine mesh) 75 Thus, a fiber extracted from any source which meets these criteria can be used in the food product of the present invention. This method is a crude determination. Other techniques such as image analysis or microscopic examinations for fiber length can be used. The fiber used in the food product of the present invention can be obtained from any plant source which has a high content of insoluble dietary fiber. Alternatively, fibers can be obtained from microbial sources such as fermentation products, for example, cellulose. Fiber is intended herein to mean a material which is predominately cellulose in nature. Examples of some preferred fibers are cellulose, hemicellulose and lignin. A high content of insoluble dietary fiber is described herein as greater than 75% of the fiber used in the food product of the present invention. The fiber can be obtained from sources such as, but not limited to, oat fiber, corn fiber, wheat fiber, sugar beet fiber, rice fiber and wood fiber. Certain sources of fiber such as soy fiber and pea fiber are not suitable for use in the present invention because the fiber lengths are too short, i.e., less than 100 microns, and cannot adequately strengthen the material. Techniques which would lengthen pea or soy fibers would render these fiber sources usable in the present invention. A structurally reinforced food product can be made by admixing the fiber to traditional ingredients used to make the food products. As shown in Example 1, both sugar cone and wafer cone formulations can be used and require little if any changes in the ingredients and processing steps that are commercially in practice. Depending upon the formulation, it may be necessary to add more water to the fiber fortified recipe. A like amount of flour can be removed from the formulation to compensate for the addition of the fiber. The food product of the present invention includes, but is not limited to, edible wafers for frozen desserts and refrigerated novelties, such as ice cream cones; formulated foods derived from grains which include baked foods, (e.g., crackers and cookies) snack foods, (e.g., corn chips) puffed foods (e.g., cereals) and extruded foods (e.g., tortillas). The food products of this invention are those which are derived from grains derived from wheat, oat, barley, rice, soy and the like. In one embodiment, as described in Example 1, the long insoluble fiber strands are added to an edible wafer mixture (e.g., sugar ice cream cone) which can be shaped in wafer form, cone form or tubular form. The long insoluble fiber strands of Example 1 are in the form of oat fiber as described in U.S. Patent No. 5,023,103 the teachings of which are incorporated herein by reference, and is referred to herein as OPTA™ oat fiber 770. OPTA™ oat fiber 770 is a delignified, unbleached fiber product which is prepared by alkaline treatment of oat hulls under high temperature, followed by washing and grinding. The OPTA™ oat fiber 770 has a high dietary fiber content in excess of approximately 90%. In Example 1, the OPTA™ oat fiber 770 is added at 1-2% by weight of the total ingredients of a sugar ice cream cone mixture (oat fiber) . As demonstrated in Example 1, the ingredient typically removed from the standard sugar ice cream cone mixture (control) is flour. However, other adjustments to the wafer mixture of the present invention may be necessary, such as addition of water to maintain the taste and sensory profile of the final product. Those skilled in the art will be able to determine other suitable wafer mixtures which contain the fibers of the present invention using no more than routine experimentation. As demonstrated in Examples 2-4, the sugar ice cream cones containing the OPTA™ oat fiber 770 were sensorially harder and firmer than the control sugar ice cream cones (cones which did not contain the OPTA™ oat fiber 770) and showed greater resistance to breakage. Example 2 describes the sensory texture profile of the sugar cones containing the oat fiber versus the control sugar cones using a panel of five unskilled judges. The results demonstrate the superior hardness and firmness of the sugar cones containing the oat fiber as compared to the control cones. In addition, the experiments in Example 3 were conducted to measure the ability of each sugar cone (oat fiber sugar cone and control sugar cone) to regain its shape after compression (G') and the ability of each sugar cone to deform after compression (G") . In both instances, the sugar cones containing the oat fiber proved superior in their ability to regain their shape after compression and to deform after compression. Finally, Example 4 demonstrates the three point bending test which measures the force required to break the sugar cones. The break force for the control cones was 75 g, while the cones containing the oat fiber remained intact at a force of 100 g, which is the limit of the instrument. In another embodiment, described in Example 5, the long, insoluble fiber strands are added to a snack cracker mixture in the form of oat fiber as described in U.S. Patent No. 5,023,103, the teachings of which are incorporated herein by reference, and is referred to as OPTA ™ oat fiber 780. OPTA™ oat fiber 780 is a delignified, bleached oat fiber. The OPTA™ oat fiber 780 has a high dietary fiber content in excess of 90% by weight and is produced using the same process for OPTA™ oat fiber 770, but hydrogen peroxide treatment is added after the alkaline treatment. In Example 5, two types of rotary cut snack crackers were prepared. Both mixtures contained 1-2% OPTA™ oat fiber 780, but one mixture contained 19% by weight water (A) of the total ingredients and the other mixture contained 21% by weight water (C) of the total ingredients. As demonstrated in Example 6, the relative strength of each snack cracker was superior to their respective control snack crackers (i.e., like snack crackers which did not contain the oat fiber) indicating that even in the presence of higher amounts of water, the addition of oat fiber to the product improves its overall strength. Other adjustments to the cracker mixture using the fibers of the present invention and resulting in structurally superior crackers, can be made by those skilled in the art using no more than routine experimentation. In a further embodiment, described in Examples 7-9, extrudates containing wheat starch or corn meal with varying amounts of OPTA ™ oat fiber 780 were prepared and tested for their relative strengths as compared to a like product which did not contain the fibers of the present invention. As shown in Example 8, the strength of the wheat starch extrudates containing 2-10% OPTA oat fiber were structurally superior to the controls. In addition, corn meal extrudates containing 2% OPTA ™ oat fiber were structurally superior compared to a like product which did not contain the fibers of the present invention, as shown in Example 9. Example 10 describes another embodiment which demonstrates the ability of OPTA™ oat fiber to reduce the fines or small particles in a flaked, ready to eat (RTE) cereal. In this embodiment, varying amounts of OPTA™ oat fiber were added to a bran flake mixture; the integrity of the flakes were tested and compared to a control (like bran flakes which did not contain the OPTA™ oat fiber) . As shown in Example 10, as little as 1.7% by weight OPTA™ oat fiber in the bran flake mixture resulted in measurable decrease in fines (3%) and addition of 3.5% by weight OPTA™ oat fiber to the bran flake mixture resulted in a significant decrease in fines (29%) . In addition to the delignified unbleached OPTA™ oat fiber 770 and 780 described above, other forms of fiber extracted from a suitable source as described herein, such as non-delignified bleached fiber; non-delignified unbleached; unbleached, partially delignified fiber; bleached or unbleached delignified fiber, can be used in the wafers of the present invention. Food products containing the fibers can enhance the shelf life and eating quality of the product. This invention will result in reduced breakage (hence product loss) of food products such as ice cream cones and cookies, during manufacture, packaging and shipment of the food product, thus resulting in the consumer receiving a superior product. In addition, the presence of fibers of the present invention allows for a greater water content in some food products while still maintaining a structurally superior product, thus reducing production costs. The invention is further illustrated by the following examples, which are not intended to be limiting in any way. Example 1. Preparation of Ice Cream Cones Containing the OPTA™ Oat Fiber 770 and a Control Sugar ice cream cones which contained the OPTA™ oat fiber 770 (Oat Fiber) and sugar ice cream cones (control) which did not contain the OPTA™ oat fiber 770 were prepared using the following formulation and procedure: Control Oat Fiber Ingredient Grams %) Grams ( % ) Soft flour 100 (40.48) 100 (39.88) Granulated Sugar 25 (10.12) 25 (9.97) All-purpose shortening 1 (0.40) 1 (0.40) Opta oat fiber 770 0 3.7 (1.48) Salt 0.5 (0.20) 0.5 (0.20) Water 120 (48.58) 120 (47.87) Flavor, color, potassium sorbate 0.5 (0.20) 0.5 (0.20) The specifications for the flour used are as follows: protein 9.5 - 10.5%; ash 0.41 - .44%; pH 4.7 - 4.85. Any equipment which can produce a smooth, lump-free batter is suitable. The dry ingredients were first blended then the water is added slowly and mixed for 15 minutes. The melted shortening was then blended followed by mixing for an additional minute. The batter was placed in the molds and was baked. Example 2. Sensory Texture Profiling of the Oat Fiber Recipe and the Control Sensory texture profiles were obtained with a panel of five unskilled judges. The samples coded (1) Oat fiber recipe and (2) Control, were tested for hardness, firmness, crispness and crunchiness. The mean scores on a five-point scale are as below: Attribute Sample 1 Sample 2 Hardness 4.67 4. Ϊ7 Firmness 5.0 4 . 2 Crispness 4.6 4 . 8 Crunchiness 4.6 4 . 6 As demonstrated above, the Oat fiber recipe was sensorially harder and firmer than the Control. A sample evaluation sheet used in this evaluation is presented below.

Crunchiness —as above— Low - High 1 2 3 4 5 SCORES: Sample 1 Sample 2 Hardness Firmness Crispness Crunchiness Example 3. Small Amplitude Oscillatory Measurements of the Oat Fiber Recipe and the Control These experiments were conducted on the cones made with the oat fiber recipe and the control cones, described in Example 1, to measure the ability of the cones to regain their shape after compression (C) and the ability of the cones to deform after compression (G 1 *) . Sample strips of each type of cone were placed in a small amplitude oscillator which rotates the strips while applying a force upon the strips. The small amplitude oscillator measures the angle or distance moved by the strips in radian/second to determine G' and G". Sample strips were prepared by steaming the cones, opening them out and cutting them to the required size of 41.8 x 8 x 2.2 mm. The strips were air dried at 50°C to the characteristic moisture content and then used for the small amplitude oscillatory measurements. The small amplitude oscillatory measurements on each sample were in the range of 0.1 radian/second (rad./s) to 100 radian/second (rad./s) at a strain level of 0.1%. The strain level was selected based on the strain sweep data obtained at a frequency of 6.28 rad./s. Figure 1 gives the results for the storage modulus G' (the ability of the material to regain its shape after compression) and the loss modulus G" (the ability of the material to deform after compression) for the strips from the control cones and the cones prepared with OPTA™ oat fiber 770. The values obtained for the strips containing the oat fiber are higher than those of the controls, thus indicating the ability of the material to regain its shape after compression and the ability of the material to deform after compression is greater in the strips containing the oat fiber. Example 4. Three Point Bending Test of the Oat Fiber Recipe and the Control The measurements were conducted on a Rheometrics Solids Analyzer-II (RSA-II) . The strips used were prepared as described in Example 3. The only difference was the dimension of strips which were 50 x 9 x 2.2 mm. The small amplitude strain sweeps were conducted in the range of 0.00001% to 0.01% at 6.28 rad./s. The results are plotted in Figure 2. The break force for the control strip is 75 g while the oat fiber containing strip remained intact to 100 g which is the limit of the instrument. The results indicate that the cones prepared with the oat fiber show greater resistance to breakage. Example 5. Preparation of a cracker Containing OPTA Oat Fiber 780 The following formulation and procedure was used to prepare two types of rotary cut snack crackers containing OPTA ™ oat fiber 780 (Oat fiber) . Both mixtures contained 1-2% OPTA ™ oat fiber 780, but one mixture contained 19% by weight water (A) of the total ingredients and the other mixture contained 21% by weight water (C) of the total ingredients. In addition, control snack crackers were prepared for snack crackers A and C, (B and D, respectively) which contained equivalent amounts of water but did not contain OPTA ™ oat fiber 780.

The rest of the ingredients were added and then mixed in a Hobart mixer with a 40 quart bowl and paddle agitator for 10 minute on low speed. Each dough was passed through a three roll dough sheeter and two sets of reducing rolls to a dough thickness of approximately 2 mm. The dough sheet was docked and cut into round pieces using a two roll docking and cutting system. The crackers were then baked in a 30 foot indirect fired traveling band on a heavy duty Ashworth mesh band. The baking time was 6 minutes at an average baking temperature of 460°F. The % finished moisture of the final products were as reported above. Example 6. Three point bending test of the crackers These test were conducted on the crackers made with the oat fiber recipe and the control crackers, described in Example 5. The force required to break a cracker was measured on a TA.XT2 Texture Analyzer using the three point bending test. The crackers were placed on 2 supports placed 3.2 cm apart. The probe (0.3 x 7 cm) was centered above the supports and lowered at a speed of 5 mm/sec through the cracker until the cracker broke. The maximum force during the fracture was recorded as the strength of the cracker. The results, tabulated below show the relative strengths of each type of cracker compared to its control cracker. The data indicates that in the presence of varying amounts of water, the addition of the oat fiber yields a product that is structurally superior to like product which does not contain the fiber.
